ELECTRIC FAN WITH HEATING ATTACHMENT Peter Varis, Long Beach, Calif.

Claims. 1

My invention is an improvement in fans, especially power-driven fans forcirculating air and equipped with means for heating air when a rise intemperature is needed.

An important object of my invention is to provide a circulating fan,operated preferably by electric. current, and mounted so that it can beadjusted to change the direction of the air current which it creates;and equipped with a heating member and means for energizing said memberwhen desired.

A further object is to provide such a fan of efficient construction, andhaving a suitable support upon which the fan is securely mounted.

Other objects are made apparent in the following description, and apreferred embodiment of the improved fan is illustrated in the drawings.But this disclosure is explanatory only, and the construction set forthherein can be changed in various details without deviation from theessential characteristics of the invention as defined in the appendedclaims.

On said drawings:

Figure 1 is a side view of a fan according to this invention.

Figure 2 is a top view on a larger scale, viewed from the plane of line2-2 in Figure 1.

Figure 3 presents a detail; and

Figure 4 is a diagrammatic view showing the interaction of the blades ofthe fan with the deflector elements for distributing the air which thefan sets in motion.

The body of the fan comprises a hub l to the rim of which are afiixedthe blades 2. The fan has the approximate shape of half a sphere withthe huh I at a pole thereof and the blades joined at one end to the hubl. The blades curve outward and extend away from the hub I, and theother ends are united by a ring 3. The cage-like framework of the fan isrotatable and is made fast to the lower end of a vertical shaft 4carrying the armature of an electric motor in a casing 5. This casing issecured to the lower end of a rod 6, adjustably connected to a post Iaffixed to a base 8. The fan can be made to operate in the positionshown on Figure 1, or swung up to a position in which the hub I isuppermost, or at any intermediate position.

Enveloping the fan is a second stationary framework comprising elongateddeflector strips 9, curved so as to be convex along their outer edges.These deflector members are affixed at one end to a ring In that isapproximately in the plane of the huh I; and at their opposite ends to aring H which is a little beyond the plane of the ring 3. This ring isjoined by rods or connectors l2 to a hub l3 fixed upon the rod 6 betweenthe ring 3 and the top of the post I. The cage-like framework includingthe deflectors 9 is thus hung upon the rod 6 and cooperates with theblades 2 in distributing the air in all directions.

Between the ring II and the housing 5 of th 7 motor is a heater membercomprising a disk [4 of insulating material made fast to the rod 6. Thedisk has radiating arms l5 carrying electrical resistancecoils I6extending in several parallel lines around in the space between the diskl4 and the blades 2. The elements l6 are attached to binding posts H onthe disk l4, and to these posts are connected the ends of electricalcon-- These conductors 18 which supply, current. ductors are enclosed bythe post 1, which is hollow, and run to the base 8, which carries aswitch IS. The base has terminals so arranged that the switch can closea circuit to energize both the motor in the housing 5 and the heatertogether, or the motor only. Hence air at ordinary temperature can beset into motion, or the air can be heated as the fan revolves. Theswitch terminals in the base 8 will be joined to an ordinary flexibleconductor with a plug at one end for insertion into an outlet of awiring system.

The upper end of the rod 6 has a forked element 20 with openings in botharms for a bolt 2| to be passed through the end of the post I betweenthe two arms of the element 20. The bolt is made fast by a wing nut 22.The element 20 has a threaded stud 23 by which it is screwed to theupper end of the rod 6. On the post I adjacent the element 20 are upperand lower stop projections 24. Hence the fan and the deflectors can besecured with the hub uppermost or lowermost, or at any point betweenthese extremes. The blades 2 and 9 can be disposed in any relativeposition, with the blades 9 at an angle to the blades 2, as illustratedin Figure 4; and with the planes of the blades all in planes that passthrough the axis of the shaft 4 or at any angle to such planes as willensure effective operation and parts of a room.

Having described my invention, what I believe to be new is:

1. Apparatus comprising a cage-like framework containing fan-blades anda cage-like the hub is affixed, a motor casing bearing said shaft, a rodsuspending said casing in fixed posi-- tion, and a hemi-sphericalcage-like framework afiixed to said rod and having deflector bladesenveloping the first-named framework, said apparatus also having aheater member aflixed to said rod and disposed within th first-namedframework.

3. Apparatus comprising a hub, fan blades affixed thereto and curved toform a hemi-spherical.

cage-like framework, a rotatable shaft. to which the. hub is affixed, amotor casing bearing, said shaft, a rod suspending. said casing in fixedposition,,and a hemi-spherical cage-like. framework affixed to said rodand having deflector blades enveloping the first-named framework, saidappa ratus also having a heater member affixed tosaid rod and disposedwithin the first-named framework, a postlto which said rod is adjnstablyconnected, abase for the post and. a switch on the. base to control themotor and heater member.

4. Apparatus comprising a hub, a rotatable shaft carrying said hub, ahousing for an electric motor, fan blades secured at one end to the;

hub, a ring joining said blades at the opposite ends, a frameworkcomprising deflector blades and rings uniting the'adjac'ent ends thereofensaid motor;

4 veloping said fan blades, a rod affixed to said casing, said frameworkbeing made fast to said rod and a support to which said rod isadjustably connected, said apparatus also having an electric heatermember adjacent one end of said fan blades and enveloped by said blades,means for securing said member to said rod and a switch on said supportfor said member and said motor. 5. Apparatus comprising a hub, arotatable shaft carrying said hub, a housing for an electric motor,curved fan blades secured at one end to the hub, a ring of largerdiameter than the hub joining said blades at the opposite ends, aframework comprising curved deflector blades and rings uniting theadjacent ends thereof enveloping said fan blades, one of the last-namedrings encircling the ring joined to the fan blades, a rod afiixed tosaid casing, a bearing on said rod,

' radial connectors joining said encircling ring to said bearing, asupport to which said rod is adjustably connected, said apparatus alsohaving an. electric heater member adjacent one end ofsaid fan blades andenveloped by said blades, said member comprising a disk of insulationsecured to saidv rod, and aswitch for said member and PETER VARIS;
